Hello @Ganesh Kumar Sivagurunathan (CIS) !

These are the things to consider as restrictions :

• You can't yet switch from or to an Ultra Disk or a Premium SSD v2, you must deploy a new one with a snapshot of an existing disk. See Migrate to Premium SSD v2 or Ultra Disk for details.
• You can only change disk type twice per day.
• You can only change the disk type of managed disks. If your disk is unmanaged, convert it to a managed disk with CLI or PowerShell to switch between disk types.
• To use Premium managed disks, your VM must use a VM size that supports Premium storage. This example also switches to a size that supports premium storage
